Hi guys

I have email account @hotmail.com (outlook.com), recently the old emails I have since august 2013, I cannot find. this is always happening with Hotmail account only and I can find the lost mails in pop folder or delete folder. but this time I cannot find everywhere and they are important as they contain link and serial numbers for software (original).

in Hotmail settings I used 2 way verification so no one can hack my account, but now Im not sure about this. please help me if you can

thanks
